An ice chest at a beach party contains 15 cans of soda at 5°C. Each can of soda has a mass of 0.36 kg and a specific heat capacity of 3600 J/(kg·°C). Someone adds a 6.2 kg watermelon at 28°C to the chest. The specific heat capacity of watermelon is nearly the same as that of water. Ignore the specific heat capacity of the chest and determine the final temperature T of the soda and watermelon.
